We divide 858691 by 77
Our goal is to divide 858691 by 77.

Going ahead to step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 77

Advancing to step 2:
77 goes into 85 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 77 from 85 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 77

Going ahead to step 3:
If we divide 88 by 77, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 77 from 88, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 77

Let's proceed to step 4:
When dividing 116 by 77, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Deduct 77 from 116 and we're left with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 77

On to step 5:
If we divide 399 by 77, we get 5 and a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 1115.0
Subtracting 385 from 399 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 77

Step 6:
77 can be fit into 141 1 times, resulting in a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 11151.0
Subtract 77 from 141 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
640 divided by 77 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 11151.8
If we take 616 away from 640, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
When dividing 240 by 77, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 11151.83
Subtracting 231 from 240 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
77 goes into 90 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 11151.831
If we subtract 77 from 90, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
77 can be fit into 130 1 times, resulting in a remainder of 53.
The next digit of our result is 1. 
Result so far: 11151.8311
If we subtract 77 from 130, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

In conclusion, the division gives 11151.8311 with a balance of 0.00053.
